2020-8-14 silver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000 ...

This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

This is because gold almost always occurs as the metal, whereas silver may be present in the ore in many different chemical forms, some of which are not cyanide soluble. Gold recovery efficiency from operating heap leaches is typically ∼70%, although it can range from 50% to 90%.
